I never had one work on one side only but I did have a similar problem with a 76 after putting in a 350, it had a 6 cyl. before and etc. and once back together ps wouldn't work. We done exactly as listed above, jacked it up, ran it back and forth several times with the cap off the ps pump and all was well.

**Dieselwrencher** · 12-01-2010, 04:19 PM

It very well could have an air pocket in it or the worm gear or something could be rusty from sitting without fluid while torn apart.

palposity · 12-02-2010, 09:42 PM

Well I got a bunch of work done on Cletus today. I tried the trick of jacking up the front end and running the wheels back and forth. No difference. Power steering is spotty at best. I also have no pedal on the brakes. After bleeding the brakes twice I'm starting to think I have a bad Master Cylinder. I was hoping to take the truck to the local muffler shop to be fitted with an exhaust system tomorrow, but with no brakes/steering I'm going to hold off till I get those issues resolved.

I also got the interior put together today. Just missing a couple of trim pieces on the doors. But we'll have her together soon!

MTCK · 12-02-2010, 10:45 PM

Good progress! I would try to bench bleed the MC before buying a new one. I had a truck apart for an extended period of time and could not get the air out of the system until I removed the master cylinder and rebled it on the bench. Good luck - almost there!

Just messin' with ya. I'll post some this weekend.

cable666guy · 12-03-2010, 04:46 PM

Great build, man!! You'll be plowing in style this season!! Keep it up, you're right there...

palposity · 12-03-2010, 04:54 PM

thanks buddy

*nbpro* · 12-03-2010, 06:55 PM

good to see you're making some headway. just keep plugging away, you'll eventually get there. i've enjoyed reading your progress. keep up the good work.

**Dieselwrencher** · 12-03-2010, 09:59 PM

Looking very nice. Keep up the good work. Atleast someone is getting something done on their projects. Because I know I haven't.

palposity · 12-04-2010, 02:40 PM

Thanks guys. I'm having horrible problems with the brakes though. I need some advice. I have bench bled the MC, then all the brakes, and no pedal. Then I replaced the MC with a known good one, bench bled, then bled all brakes. No pedal. I checked for vacuum to the booster and there is definitely suction on the line going to the booster. No fluid leaks anywhere. I'm flummoxed. Anyone got ideas?

*nbpro* · 12-04-2010, 02:51 PM

i had friend went through something similar. It turned out to be bad SS brake lines. They were letting air into the system but not leaking any fluid.

Thanks, but that is a very scary answer considering I used all new SS brakes lines on this build. I guess I'll go around and double check that they are all good and tight, and if I find anything lose I will re-bleed the brakes (again).

MTCK · 12-04-2010, 03:20 PM

Hmmmm could it be your proportioning valve? If you try to pump up the brakes do you get a brake warning light (and slight clicking sound from the valve)? That would indicate a difference in pressure front/rear, which might help you pinpoint the problem.

When I bought my truck the PO said he couldn't get the brakes to bleed, and I sort of chuckled. Then I couldn't make them bleed either.... I had to bench bleed the crap out of the MC and then used a motiv power bleeder to push new fluid through the whole system. It has worked like a champ ever since. I left the MC full with plugs in when I installed it after the bench bleed, and very quickly pulled the plugs and installed the lines, then immediately slapped the power bleeder on and bled the system.

I don't think so. I am consistently getting air in the line in the rear brakes. No visible leaks so I have to figure out what the deal is.

palposity · 12-04-2010, 06:28 PM

Pics of interior just about done. I still have to clean up the steering wheel and column quite a bit.

glimmertwin01 · 12-04-2010, 07:16 PM

i notice an older style speedo..... nice work..sorry about the brakes thats rough man

Sarge261 · 12-04-2010, 07:46 PM

That interior is SWWWWEEEEETTTT!!!!!!! Is that the dash cover stich is making if so could I (we) get a better picture of it?

As for the brakes is it just the rears you are havng air issues with or the fronts too? I am wondering about the proprtioning valve myself, also did you have the rear load sensing valve still installed or is it gone. I had a really soft pedal and couldnt bleed my rear brakes and that valve was bad.

Looks good, and have you been missing the snow or have you got some.

I need to get to work on my truck too, but I cant get motivated... maybe next weekend

I guess it is! That was the speedo that was with the truck when I bought it. You are right though, if it was the factory one it would be an 85MPH unit. Thanks bud!

Yeah who knows on the brakes. What I do know is that I am out of time. We have snow in the forecast all week this week. I was planning on taking the truck to the local shop to have them make me up a nice dual exhaust system Monday. I guess I will have them look at the brakes too and see what is up. Oh, and I do not have the rear load sensing proportioning valve installed anymore - just the one up front and it was working great before I started this whole fun journey.

Yes, that is my "Stitch made" interior. He did the seat, the door panels, and the dash. I'll post up some pics after my Monday jaunt to the muffler shop.

Sarge261 · 12-04-2010, 11:22 PM

Thanks,

Hopefully its just something that was just over looked and simple.

Sarge

palposity · 12-05-2010, 10:12 PM

Loaded the truck up on the trailer for a trip to the muffler/brake shop tomorrow. I decided this was a good time to snap some undercarriage pics. Also the power steering pump developed a leak. (see red fluid drips in snow).

glimmertwin01 · 12-05-2010, 10:15 PM

nice...almost too nice to plow with
got my plow on the 77 K5 installed tonight.... got about 8 inches today
